GLM Z1 32B 0414 — Hardware Requirements & GPU Compatibility

ChatFunctions

GLM-Z1-32B-0414 is a 32-billion-parameter dense reasoning model from Z.ai (formerly Zhipu AI), built on GLM-4-32B-0414 through cold-start training, extended reinforcement learning, and extra work on math, code, and logic. It produces a long chain of thought before answering and is notably stronger at mathematics and complex multi-step problems than its base model. The card says it is comparable to larger models such as DeepSeek-R1 on some benchmarks. A Q4 quant takes about 19 to 20 GB, so it fits a 24 GB GPU with a modest context, or a Mac with 32 GB of memory. The context window is 32,768 tokens, shorter than many newer reasoning models, and thinking traces consume part of it. It is released under the MIT license, so commercial use is unrestricted. The card recommends a temperature of 0.6, top-p of 0.95, and top-k of 40. It supports English and Chinese, and the same release includes a 9B sibling and a rumination variant for open-ended research tasks.

Works on macOS, Windows and Linux.

Install Ollama (Linux)
$curl -fsSL https://ollama.com/install.sh | sh
Install Ollama (macOS / Windows)
Download and run the app; it installs the ollama command.
Download Ollama ↗
Run Q4_K_M
$ollama run hf.co/bartowski/THUDM_GLM-Z1-32B-0414-GGUF:Q4_K_M
Raise the context window
Type it inside the chat. For the API server instead, start it with OLLAMA_CONTEXT_LENGTH=16384 ollama serve.
$/set parameter num_ctx 16384
A larger context needs more memory than the weights alone.
Use the API
Ollama serves its API on http://localhost:11434.

Frequently Asked Questions

How much VRAM does GLM Z1 32B 0414 need?

GLM Z1 32B 0414 requires 20.0 GB of VRAM at Q4_K_M, or 65.6 GB at BF16. Full 33K context adds up to 1.9 GB (21.9 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 32.6B × 4.8 bits ÷ 8 = 19.5 GB

KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 2.4 GB (at full 33K context)

Can I run GLM Z1 32B 0414 on a Mac?

Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run GLM Z1 32B 0414, the smallest at IQ2_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 20.0 GB of usable unified memory (RAM minus macOS overhead), from Mac Mini M5 Pro (24 GB).

Can I run GLM Z1 32B 0414 locally?

Yes — GLM Z1 32B 0414 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is GLM Z1 32B 0414?

At Q4_K_M, GLM Z1 32B 0414 can reach ~240 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~33 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 20.0 × 0.65 = ~260 tok/s
